The Quatum speed limit (QSL) is defined as a lower bound of the time for the quantum state to evolve from the initial state to the final state [1]}, [2]}, [3]}, [4]}, [5]}, [6]}.
Here we derive the QSL for the dynamics under the stochastic noise given by (REF ).
First, let us focus on the Bures angle

L(t) =arccos{| 0|(t) | }
